It’s finally here. My book, Hooked: How to Build Habit-Forming Products, is now available. 
Over a year ago, I promised my blog subscribers I’d make them a little e-book summarizing my research — I thought it would be 20 pages or so.
However, as the project evolved, it turned into something bigger. Fortunately, I met Ryan Hoover, who helped me push the book to completion. I also received the generous help of hundreds of blog subscribers who contributed to the book.
Today, I’m proud to bring you the finished product!
Hooked will go on sale soon in print ($29.95) and ebook format ($9.95). However, as I promised, blog subscribers get it for free.
But there’s a catch!
Amazon will only let me give the book away for $0 for five days.
To get your download, go to this link from December 27 to December 31.
One more thing
The book is yours free just for reading my blog, however, I need your help.
When you’re ready, please take a minute to write a review on Amazon and GoodReads. If you read an early version of the book, please leave a review now.
Early reviews are critical and your help is very much appreciated. Thank you!
Of course, feel free to email me with any edits or suggestions.
I hope you enjoy Hooked.
